4.2.4 Trigger Setup
Trigger Angle -
°°°°
BTDC
This field defines the angle in
°
BTDC at which the ECU will be triggered. The ECU
uses this value to calculate the time for the next ignition so it is important that this
value is correct since it will affect the base ignition timing. This setting also appears in
the Ignition Set-up page for convenience.
Trigger Type
This field defines the trigger pattern the ECU will see coming from the crank or
camshaft angle sensors. The E6GMX is fixed to Standard trigger.
Trigger Input
This field defines the type of pickup used to trigger the ECU. The E6GMX is fixed to
Hall effect.
Trigger Edge
The trigger edge defines whether the ECU uses a rising or falling signal from the
pickup. For a further description on trigger edge see the appendix.
Trigger Pull-up
The Trigger Pull up setting is only used when in Hall Effect mode. The Trigger pull
up is needed for most Hall Effect sensors to make sure the input signal operates of the
full 0 – 5v range. For GM engines running the factory ignition module, this setting
will need to be set to “Trigger pull-up off”. For a further description on trigger pullup
see the appendix.
